To strengthen case-based instruction for professional degree graduate students and enhance the quality of graduate education, the Ministry of Education initiated the development of a case database for professional degrees in 2013. Currently, the Education Professional Degree Case Database has become a vital platform for training graduate students in education professional degrees in China, eff ectively driving reforms in university training models for these students. The continuous supply and in-depth application of high-quality instruction cases in the database are crucial for enhancing the quality of master of education programs. This paper employs statistical analysis and thematic analysis to examine 47 geography instruction cases in the said database. The fi ndings reveal that the number of cases is growing steadily, with case development characterized by participation from many universities but concentrated among a few. The cases in the database have largely aligned with the courses prescribed in the training programs. The selected instruction cases are concentrated in high school geography, and the case themes center on teachers’ professional growth and the cultivation of core competencies, forming seven closely interconnected thematic units. To further improve the quality of geography instruction case development, it is necessary to diversify case topics, strengthen collaborative case development, accurately grasp the essential characteristics of cases, and focus on contemporary trends in the fi eld, thereby achieving high-quality training for master of education in geography students.
